摘　　要：加速器驱动次临界嬗变堆是嬗变处置高放长寿命核素的有效装置之一。为高效嬗变次锕系核素(MA),本文提出一种工业加速器驱动次临界嬗变堆的设计方案,该方案采用铅铋合金作为冷却剂和散裂靶材料,燃料采用金属弥散体形式,堆芯采用三区不同惰性基质份额布料方案,运行功率为800MWt,循环长度为600有效满功率天,MA的嬗变率可达到328.8kg/a。Accelerator driven subcritical systems are considered as one of the high-efficiency transmutation devices for the handling of high-level radioactive wastes. An industrial-scale accelerator driven minor actinide （MA） burner system was proposed. The lead-bismuth eutectic alloy was chosen as the coolant and the spallation target material, and the metallic dispersion fuel was adopted to adapt for high burnup. The whole core uses three fuel zone loading scheme with the thermal power of 800 MWt and the cycle length of 600 EFPD （effective full power day）. It is indicated that the transmutation rate of MA can be achieved as high as 328.8 kg/a.
